SUCKLING ARRANGEMENT FOR PIGS.

Specification of Letters Patent.

Application filed September 16, 1907.

Patented Sept. 15, 1908.

Serial No. 392,991.

To all 'whom it may concern:

Be it known that I, AUGUST GRNENWALD, a subject of the Kingdom ofWrtemberg, residing-at Hohentwiel, in the Kingdom of Wrtemberg andEmpire of Germany, have invented certain new and useful ImprovementsSuckling Arrangements for Pigs, of which the following is aspecification.

In raising domestic animals, particularly pigs, it is frequentlynecessary to feed the young animals by means of artificial sucklingarrangements.

The present invention is an improved suckling apparatus and consists ofa novel milk vessel provided with the sucking tubes containedrwithin acasing supported horizontally and controlled by springs adapted to allowturning or rocking movements of the vessel but which will always returnthe vessel to initial or normal position when not being used. Thesucking tubes are attached to the vessel in such a manner that the milkor liquid food can be drawn from the lowermost part of the vessel andthe tubes are so arranged that an unintended flow will not occur.

The accompanying drawings illustrate the invention, and

Figure 1 is a plan view of the suckling apparatus, partly in section.Fig. 2 is an end view thereof. Figs.` 3 and 4 are transverse sectionsthereof, showing different arrangements of the sucking tubes.

TheV milk vessel a is preferably made of acid proof material such aspottery, and is closed at both ends by screw caps l) and has a refillingtube c, which is likewise closed by a screw cap d. The vessel has anumber of small openings to which are connected the inner ends ofsucking tubes f in any suitable manner, and on the outer ends of tubes fare rubber nipples g. The sucking tubes f are fitted to the milk vesselin such a manner that the milk cannot escape by gravity or siphonagethrough said tubes; and further when the tubes are sucked the milk iswithdrawn from the lowest part of the vessel, so that the milk cannotchoke the sucking animal, nor run out when no animal is sucking.

In Fig. 3 the sucking tubes are connected to the top of the vessel andextended thereinto so as to dip from above into the milk.

In Fig. 4 the tubes are'connected to the lowermost part of the vesseland lead back around and over the vessel to the outlet.

The milk vessel is contained in a casing,

preferably made of wood and lined with insulating or non-heat-conductingmaterial h, said casing being preferably divided longitudinally into twoparts hinged together as at lc, so as to permit removal of themilk-vessel.

The casing has trunnions l on its-ends by means of which it is supportedon brackets m, which are so made that the casing can move slightly'horizontally and also turn on its axis.

On the front side of the casing where the sucking tubes f open, a lightleather bolster n is secured to the casing by means of leather straps 0.This bolster prevents the animals injuring their noses and mouths whenseizing the rubber nipples g. To the top and bottom of the casing areconnected spiral springs p, the other ends of which are attached to thesupporting board q. These springs normally hold the casing in theposition shown in Figs. 3 and 4, but allows the sucking animal to pullthe nipple forward and up and down at will,

the springs p always returning the casing to normal position whenreleased.

The milking apparatus is particularly adapted for pigs; it allows thepigs to pull and push the nipples in a natural manner, and it has thefurther advantage that the contents of the vessel will be thoroughlymixed up when the sucking is commenced. And all parts can be readilycleansed.

Having now described my invention what I claim and desire to secure byLetters Patent of the United States is:

l. In a suckling apparatus, the combination of a pivotally mountedcasing, springs for holding said casing in normal osition, butpermitting tilting thereof, a k vessel in said casing, and sucking tubesconnected with said vessel so as to draw milk from the bottom thereof,and extended up to the top of the casing and then down to the sidethereof, and provided with nipples, substantially as described.

2. A suckling apparatus, comprising a tiltable casing having an openingfor sucking tubes in its front side, supports on which the casing ismounted, springs connected to the casing and adapted to normally hold itin vertical position and to return it to normal osition afterdisplacement, a buffer on the front side of the casing, a milk vessel insaid casing, sucking tubes communicating with the bottom of said vesseland extending up to the top thereof and down to the opening in theJfront side of the casing, and nipples on the outer ends of said tubes,substantially as described.

3. The herein described suckling apparatus, Comprising a oylindriocasing having. an opening for the sucking tube in its front side andprovided with trunnions `on its ends, supports on Which the trunnionsare mounted, springs connected to the top and-bottom of the casing andto ixed points, and adapted to return the easing to normal positionafter l displacement, a eylindrie milk vessel in said casing, and asucking tube communicating With the bottom of said vessel and extendingup over the upper side of the vessel and doWn 15 to the opening in thefront side of the casing.

In testimony whereof I have hereunto set my handin the presence oftwoWitnesses. AUGUST GRUNENWALD. "Witnesses:
